This course offers an introduction to the functions of individual decision-makers—both consumers and producers—within the larger economic system. Emphasis is on the nature and functions of product markets, the theory of the firm under varying conditions of competition and monopoly, and the role of government in promoting efficiency in the economy.
Most people make the incorrect assumption that economics is ONLY the study of money. My primary goal in this course is to shatter this belief. During this course, we will be addressing the above questions as well as many more relating to:
-the environment
-love and marriage
-crime
-labor markets
-education
-politics
-sports
-business
My main goal is to show you the way economists think and how to use this analytical system to answer questions related not only to these and other important human issues, but to anything you end up doing with your life after this class. After all, as you will quickly find out, I believe that everything is economics!

From the lesson

Firms with Market Power

So, why is it that when you fly the person sitting next to you in the plane probably paid a different price for the ticket than what you paid for it? And why does Starbucks charge so much for its coffee even though you can buy coffee at Dunkin’ Donuts for almost half of that price? This module we are finishing our discussion of the firm by focusing on cases that should be more familiar to you than the perfect competition examples we have been using.
